+## Distributed JMeter
+Distributed JMeter application is a load generator application which was developed for CloudScale project, but it can be
+ used independently from CloudScale project. For generating the load it uses the opensource software Apache JMeter.
+Distributed JMeter can be deployed on AWS or OpenStack. For more information how to do it, see below.
+
+You can read more about CloudScale project on: http://www.cloudscale-project.eu
+
+## Configs
+
+Settings in config files are separated into sections for easier understanding.
+
+### Amazon Web Services
+
+**[SHOWCASE]**
+
+```autoscalable``` - It's value ```yes``` or ```no``` tells application if showcase is deployed in autoscalable mode. This is important for getting the data from AWS.
+```host``` - The host name where showcase is deployed. Showcase must be deployed on ```/showcase-1-a``` path
+```frontend_instances_id``` - The name of frontend instances of showcase. It is used for getting data from showcase instances.
+
+**[SCENARIO]**
+
+```num_threads``` - The number of threads that we want to simulate. One JMeter instance can handle 2000 VU.
+```ips``` - IP addresses of instances to deploy JMeter on. Leave empty to not use this setting.
+```jmeter_url``` - URL to JMeter distribution. You can download JMeter and modify it, upload it somewhere and replace existing URL with yours. Otherwise leave as it is.
+
+**[AWS]**
+
+```region``` - The region name where to deploy application.
+```aws_access_key_id``` - Your AWS access key.
+```aws_secret_access_key``` - Your AWS secret key.
+```availability_zones``` - Availability zones for region.
+
+**[EC2]**
+
+```instance_type``` - EC2 instance type for distributed JMeter
+```remote_user``` - Virtual Machine user name for SSH access
+```ami_id``` - Amazon Machine Image ID to provision VM from.
+```key_name``` - Only the name of SSH key for connecting to VM.
+```key_pair``` - Path to SSH key for connecting to VM. It is auto-generated.

+```identifiers``` - Name of VM for RDS database.
+
+### OpenStack
+
+**[SHOWCASE]**
+
+```host``` - The host name where showcase is deployed. Showcase must be deployed on ```/showcase-1-a``` path
+```frontend_instances_id``` - The name of frontend instances of showcase. It is used for getting data from showcase instances.
+

+```num_threads``` - The number of threads that we want to simulate. One JMeter instance can handle 2000 VU.
+```instance_names``` - Name of instances on OpenStack to deploy distributed JMeter on.
+```jmeter_url``` - URL to JMeter distribution. You can download JMeter and modify it, upload it somewhere and replace existing URL with yours. Otherwise leave as it is.
+
+**[OPENSTACK]**
+
+```user``` - User for authentication to OpenStack.
+```pwd``` - Password for user for authentication to OpenStack.
+```tenant``` - Tenant name.
+```url``` - URL to your OpenStack authentication.

+
+## Installation
+
+Before you can use distributed JMeter scripts you need to install them. You can do this by downloading the ZIP archive and then run:
+
+```
+$ python setup.py install
+```
+
+You can also install the scripts using ```pip``` tool:
+
+```
+$ pip install -e https://github.com/CloudScale-project/Showcase/distributed-jmeter/zipball/distributed-jmeter
+```
+
+## Usage
+
+### Amazon Web Services
+To run distributed JMeter on AWS edit ```bin/config.aws.ini``` file and run:
+
+```
+$ python run.py aws config.aws.ini scenarios/cloudscale-max.jmx
+```
+
+from ```bin/``` directory.
+
+### OpenStack
+
+To run distributed JMeter on OpenStack edit ```bin/config.openstack.ini``` file and run:
+
+```
+$ python run.py openstack config.openstack.ini scenarios/cloudscale-max.jmx
+```
+
+from ```bin/``` directory.

from ```bin/``` directory.
+=======
+### Description
+
+[Response generator](https://arcane-meadow-6418.herokuapp.com/) is a web application that simulates response times according to chosen distribution.
+
+Supported distributions are:
+- [uniform](http://en.wikipedia.org/wiki/Uniform_distribution_%28continuous%29)
+- constant
+- [gauss](http://en.wikipedia.org/wiki/Normal_distribution)
+- [gamma](http://en.wikipedia.org/wiki/Gamma_distribution)
+- [exponentional](http://en.wikipedia.org/wiki/Exponential_distribution)
+- [logarithmic](http://en.wikipedia.org/wiki/Logarithmic_distribution)
+- [pareto](http://en.wikipedia.org/wiki/Pareto_distribution)
+- [weibull](http://en.wikipedia.org/wiki/Weibull_distribution)
+
+Each distribution have specific parameters by which you can manipulate the end response time in seconds.
+To each distribution we added a **k** parameter which shifts the end response time for **k**.
+
+### Usage
+
+Response generator is designed to be used inside real application as a API call.
+Each distribution has it's own URL and accepts it's own parameters, parameter **k** and **test=[true|false]** parameter:
+
+* ```/uniform?a=1&b=2&k=3&test=true```
+* ```/constant?c=1&test=true```
+* ```/expo?lambda=1&k=0&test=true```
+* ```/log?mu=1&sigma=2&k=0&test=true```
+* ```/gamma?alpha=1&beta=2&k=0&test=true```
+* ```/gauss?mu=10&sigma=2&k=0&test=true```
+* ```/log?mu=1&sigma=2&k=0&test=true```
+* ```/pareto?alpha=1&k=0&test=true```
+* ```/weibull?alpha=1&beta=2&k=0&test=true```
+
+Use ```test=true``` if you want to just print the value.
+
+Use ```test=false``` if you want to actually make a delay.
+
+### Examples
+
+* Gauss distribution has **mu** and **sigma** parameters and we want to just get the value:
+
+ ```
+ /gauss?mu=1&sigma=2&k=0&test=true
+ ```
+
+* Uniform distribution has **a** and **b** parameters and we want to make a delay:
+
+ ```
+ /uniform?a=1&b=2&k=0&test=false
+ ```
+
+* Exponentional distribution has **lambda** parameter and we want to shift the end response time for 10 units and make a delay:
+
+ ```
+ /expo?lambda=1&k=10&test=false
+ ```
